404-GEN, the decentralized platform for AI-driven 3D model generation, has released the largest open-source dataset of its kind—comprised of over 21.5 million high-fidelity 3D models. Each asset includes detailed metadata, usage rights, and ownership attribution, setting a new standard for transparency and accessibility in the synthetic data space.
The release of 21.5 million open-source 3D assets—each tagged with prompt and contributor ID—makes 404-GEN’s dataset not only the largest of its kind, but also more than all existing 3D model datasets combined, according to comparisons with Objaverse. Its scale is especially notable for the Gaussian Splatting research community, where typical datasets remain orders of magnitude smaller.
This milestone would be nearly impossible to achieve through a centralized system. 404-GEN’s rapid scale is a direct result of its underlying architecture: a permissionless subnet on Bittensor where compute contributors and model developers are rewarded based on output quality. This decentralized design has enabled an unprecedented volume of synthetic 3D content to be generated, scored, and shared in record time—highlighting the production potential of decentralized intelligence and compute.
The dataset unlocks immediate value for researchers, developers, and studios looking to accelerate their pipelines with high-quality, adaptable 3D content. While a sample set is now publicly available on Hugging Face, access to the full dataset is available upon request [link to be provided], with priority given to projects advancing 3D research and development.With applications across gaming, simulation, and spatial computing, 404-GEN is shaping the foundation for the next era of digital environments and this dataset provides a foundation for others to build upon.
